Blackcomb is a 5/3-repeating regular temperament that tempers out 250/243 in the 5-limit, the amount by which three 3/2's exceed 5/4. This implies a generator of a Blackwood-like sharp fifth which is quite "dirty" but still recognizable. It possesses MOS scales of the form 1L 3s<5/3>, 1L 4s<5/3>, making it an antidiatonic tuning, 5L 1s<5/3>, and 6L 5s<5/3>. 16ed5/3 is one of the best tunings for this temperament that is not a pseudo-EDO.

Chords
Blackcomb is structured on 4:5:6 triads like octave-repeating meantone temperament. However, because Blackcomb is a much less accurate temperament, the major third and perfect fifth are usually tuned very sharp, with the major third often being closer to 9/7 than 5/4.
